Abstract
A cigarette making machine forms a tobacco stream on a moving air-pervious suction band by showering tobacco downwards through a chute which terminates in a narrow trough of which the depth increases progressively in the direction of motion of the band, with at least one air inlet for directing air obliquely downwards into the trough to pull the tobacco through the trough and towards the band. As the tobacco stream is formed on the band it acquires a depth which increases directly in accordance with the increasing height of the trough, in the direction of the motion of the band.
